duke@2 | 1 | README: |
ohair@276 | 2 | This file should be located at the top of the OpenJDK Mercurial root |
ohair@276 | 3 | repository. This root repository will include a "make" directory, |
ohair@276 | 4 | and a Makefile for building the entire OpenJDK. |
ohair@276 | 5 | A full OpenJDK repository set (forest) should also include the following |
ohair@276 | 6 | 6 nested repositories: |
ohair@276 | 7 | "jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp". |
ohair@276 | 8 | There are also several source downloads for the jax* repositories that |
ohair@276 | 9 | will be needed. |
ohair@276 | 10 | |
ohair@276 | 11 | This one root repository can be obtained with something like: |
neugens@359 | 12 | |
neugens@359 | 13 | hg clone http://hg.openjdk.java.net/jdk8/jdk8 openjdk8 |
neugens@359 | 14 | |
neugens@359 | 15 | To make sure you have all the nested repositories, you can run the |
neugens@359 | 16 | get_source.sh script located in the same respository as this file: |
neugens@359 | 17 | |
neugens@359 | 18 | cd openjdk8 && sh ./get_source.sh |
neugens@359 | 19 | |
ohair@276 | 20 | People unfamiliar with Mercurial should read the first few chapters of |
ohair@276 | 21 | the Mercurial book: http://hgbook.red-bean.com/read/ |
duke@2 | 22 | |
duke@2 | 23 | See http://openjdk.java.net/ for more information about the OpenJDK. |
duke@2 | 24 | |
duke@2 | 25 | Simple Build Instructions: |
ohair@276 | 26 | |
ohair@276 | 27 | 0. Get the necessary system software/packages installed on your system, see |
neugens@359 | 28 | http://hg.openjdk.java.net/jdk8/build/raw-file/tip/README-builds.html |
duke@2 | 29 | |
ohair@276 | 30 | 1. If you don't have a jdk6 installed, download and install a JDK 6 from |
duke@2 | 31 | http://java.sun.com/javase/downloads/index.jsp |
ohair@276 | 32 | Set the environment variable ALT_BOOTDIR to the location of JDK 6. |
duke@2 | 33 | |
ohair@276 | 34 | 2. Check the sanity of doing a build with your current system: |
ohair@320 | 35 | make sanity |
duke@2 | 36 | See README-builds.html if you run into problems. |
duke@2 | 37 | |
ohair@276 | 38 | 3. Do a complete build of the OpenJDK: |
ohair@320 | 39 | make all |
duke@2 | 40 | The resulting JDK image should be found in build/*/j2sdk-image |
duke@2 | 41 | |
ohair@320 | 42 | where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually |
ohair@320 | 43 | is 3.81 or newer. |
